ROBERT A. eALLY, or BROOKLYN, NEW YORK. MUSIC-SHEET AN D SPO QL FOR SELF-PLAYING MUSICAL APPARATUS Specification of Letters Patent.

ratented May 29, 190s;

To a, whom, it ntay concern.-

Be it known that 1, ROBERT A. GALLY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of N ewYork, have invented certain new and useful Improvements in Music-Sheets and Spools for Self-Playing Musical Apparatus, of which the following is a specification.

My invention has for its object the simplier and more perfect construction of a musicsheet and spool which will avoid error in their properly fitting together and with any self' playing musical apparatus for which they are int-ended no matter what the condition or variation of hygrometric atmospheric conditions and which spool and sheet shall also have minimum weight and be protected from deterioration or damage from natural, operative, or manual causes.

in the accompanying drawings, Figure 1 is a front view of the music-sheet wound in roll form on its spool and caught to place by its end ring. Fig. 2 is a similar view of the same rolled sheet and spool with the front end of the sheet unwound about one coils extent and pulled out to show the protective front part of sheet, Figs. 2, 2 being modified forms of end of sheet. Fig. 3 is a longitudinal section of the same roll and spool taken on its axis. Fig. 4 is a front view of same spool with the sheet unwound to its end where connected to the spool, the concluding musical chord of perforations of the selection on said musicsheet being shown in this figure. outside view of the left head of spool, and Fig. 6 is an inside view of same head. Fig. 7 is an inside view of right head of spool. Fig. S is an outside view of same hcad and Fig. 9 shows the take-up cylinder form of spool and catch.

All the views in the drawings as filed are the full working size of ordinary use except that length of spool is reduced to accommodate the width of drawing. Figs. 2 and 2 are one-eighth scaleand Fig. 9 onerprarter scale.

in my patent on compensating music spool issued March 5, 1.901, No. 66$),34f2, is

set forth a spool whose flanges are automatically adjusted to the changes of width of the paper sheet by control from hygromctric movements of paper and ventilation to the center of the roll is provided for; but no decrease of variation of the sheet is accomplished. The strip sheet or web now set forth when rolled upon its spool is greatly pr-zitectedfrom atmospheric influences, and

Fig. 5 is an whatever hygrometric changes do affect the roll are equalized to all its parts and coils by the special ventilating devices, insuring a uniform Width and fit of every part of the sheet at any one time and a very close approximation to one standard at all times.

A paper music-sheet should be protected from atmospheric changes when not in use in order to avoid any changes of dimensions laterally or longitudinally to prevent de-' terioration of its substance, to obviate puif ing or cockling, to guard it against damage or soiling by handling, and to keep all parts of the sheet of equal hygrometric condition at one time. Therefore one or more of the outer coils c c of the sheet are now shown herein as of a Waterproof or strongly moisture-resistant nature, so that when rolled up and out of use the outer part of the roll tective part of the roll maybe made by treating the front end part of the music-sheet with any suitable compound, as paraflin but I find shellac as desirable as anything, and it is espe cially good in results when applied to the outer surface only of the paper and of course does not need to extend far enough in on the sheet to affect the perforated or indicated part. Instead of treating the front end of the sheet-as just stated a piece of special-quality waterproof material may be attached to the paper sheet as a front extension or as an overlying coil, all being equivalents for the purpose stated. When the protection part is formed by treatment of the sheet itself, it is best to make the inner end of the treated part of gradually-diminishing width from edges to center, preferably a curve line, w, as by this means tearing of the sheet is avoided. It is also desir-able to have the outer coil or coiis of the roll a trifle wider than the main part of sheet, so that when the roll is wound up the outer part will lit tightly against the flanges of the spool and so completely protect the coils underneath. .ing a stripto the edge of the sheet, as S of Fig. 2, or cutting the material aii-cordingly, as S of Fig. 3: but as this is often incon. venient when the sheet itself is used for the outer protective part of roll it is economical and etiicient to split the sheet S longitudinally for a short distance at or near the front end and after spreading it sufficiently apart ICO This wide part may be made by addat the split a make any suitable joint, as by a lapped strip 8'', fastened on the inner face of r 3 5 tached back to the other edge at a V45 No. 669,342,

the sheet across and along the split, thus causing the front end of sheet to abut both spool-flanges, While the ensuing main part of sheet has a slightly-freefit, as shown in Fig. 52nearww. To insure the roll being kept closely wound when not in use and without risk of loosening from breaking of the rubber band heretofore commonly used for clasping the roll, a catch or hook h I (one or 'more) or equivalent is formed in or affixed at or near the rim of the flange or head of the spool and adjacent to the edge of the outer end of the sheet when the-latter is completely wound on the spool.

i 5 The sheet has a rin or hook g or equivalent formed in or affixe to. the edge of the outer end of the sheet S, and this ring 9 is caught over the hook it of the spool-flange to secure M others.

the sheetwhen wound on its spool. .The

same ring 9 can be conveniently and economically employed to connect the sheet to the take-up cylinder T or equivalent part of the self-playing apparatus when such cylinderor part has its engaging means It correspondz 5 ingly placed as shown in my application, Se-

' rial No. 156,623, filed May 11, 1903, Fig. 9

hereof, and covered in present claim 44; In this way one ring on the sheet can answer the two purposes stated, and its attachment to I the edge of the sheet forms a guard thereto at its edge and insures the edge of sheet being alined to the flange of the take-up cylinder. It is also preferable to slant away the sheet from the edge end where the ring is atrearward point, thus aiding the starting of the sheet in the apparatus and also its smooth finish of winding on and fastening to its own spool when rolled up and out of use.

That the music-sheet may always be exactly fitted to its spool-flanges and any variation there may be in the width of the sheet be compensated by the spool, it is best to use the compensating-spool principle of my Patent March 5, 1901; but certain modifications and improvements thereof are desirable and will now be described.

To equalize the hygrometric condition of all the coils of roll when it is wound on its spool, intercommunicating ventilation is secured between all the coils by one or more passages 19 in the inner face of the flange or head H but these are entirely Within the outer circumference of therolled-up sheet, so as to exclude external air when the roll is out of use. The passage pmay be easily made by punching out of the inner disk'only of the compositedisk head or flange H and covering the punched hole with the outer disk, These .passages 19 may also communicate by duct 1) to the interior of the inner coil or tube which connects and automatically adjusts the'two heads, and thus equalize the condition of all the interior coils of the roll. As the sheet unwinds, the passages 19 and p are opened to thelouter air to equalize all the roll to the atmosphere, which is then having access to the entire sheet as it unwinds. .As the sheet reaches the conclusion of unwindin it uncovers openings 0 into the interior 0 the inner coil or tube which connects the compensating heads,

so that the air within may be fully brought tothe same condition which has affected the sheet while unwinding As the sheet rewinds onto the spool these openings are closed by the sheet, and all parts of the roll are left to equalize This construction' avoids the tendency of sheets of many coils to change unequally in width between the innermost or outermost coils and the others when constant air access is allowed to either the outer or inner they thus have more rapid change than the i As the coils of the sheet have a slight lay between the. heads of spool to avoid 'ction in winding, many of the coils -will be slightly away from the head H and thus communicate aroundQthe the passage 1) entire circle of such coils.

To permit' the equal drying out of all the coils of the roll when wound up, ventilatin holes v are provided in the flange or head of the spool, these holes passing through the flange from its outer to inner surface 0 posite the end of'the coils of the sheet. Ahole '11 may be large enough to include all the coil coils, or both, and

ends or may be enlarged on the inner face of flange or several small holes 1: may be placed at various radial distances of the flange, and. thus collectively connect to all the coils.

Space between ends of coil and head aids distributionof the ventilation. By the ventilating and equalizing of the ends of all the coils while protecting the large surfaces of the inside and outside coils from the air when the roll is not in use sudden changesand inequalie ties of condition are avoided, yet the entire roll is capable of compensating to the aver age atmospheric condition summer or winter and when used will compensate equally in all its parts'to any special condition of the moment.

To have a light weight and compact roll and avoid danger of Warping or breaking of the heads or flanges and consequent damage to the sheet, it is best to make the heads or flanges H H of thin composite disks of press-board, aluminium, or such material,

each head composed of two. or more disks d d, the inner one, (Z, the full size to guide and guard the sheet and one. or more outer disks (1 built on to reinforce the rigidity, which outer disks can be of the same size as the in- V ner, but preferably of lesser diameter. These disks are held together by adhesive material or riveting, if desired, but are best clamped at their centers by upset thimbles' or eyelets e e, as shown, which clamping may also fasten them to suitable hubs or spindles a a to support the axial tube or wound sheet,

which hubs or spindles may be of Wood, papier-mach, &c. To secure good ventilation to the inner coil or axial tube A, it is desirable to have no large core Within it. Therefore hubs a a are made only sufficient in length .part of the spool and roll as the hub a of head H, the other parts of the spool being free to slide upon the shaft. Thus the one head H will always have a fixed position on he shaft, while the head H can slide thereon to suit the changes of width of sheet. To insure easy movement of head H and accurate true right angle of the same to the axial line, the hub a has a hole larger than the shaft, and at each. end of this hole are set eyelets or bushes e 6 preferably of substance antifrictional to the shaft and made to accurately fit and slide thereon.

The shaft R has a clutch or engagement of any suitable form, as r, to enable the roll to be turned by the mechanism of a self playing apparatus to which it may be connected for use. A fixed collar or equivalent stop 1" on the shaft R outside of and free from head H takes the thrust of the bearing of apparatus at that end and so relieves the compensating head H, tube A, and coils of sheet S from undue pressure. Adjustingscrews r r serve to regulate the lengthwise position of the spool to any apparatus. A spring presses outwardly against hub a and prevents pre. sure on head H from damaging coil A or other coils of roll.

it is evident that the hygrometrically ompensating spacing means or core A be- .weeu the two sheet-guidin g parts or heads of the spool may be formed of one or more coils of the sheet itself or of similar paper wound into a tube and to which the sheet is attached; also, that several such layers or coils may be pasted into such a tube or a self-tube of single mass be used and the sheet attached to either, so long as the coefficient of expansion of A is exactly or approximately equal to that of the sheet, as any such details are but more n'iodilications or equivalents of and tributary to my Patent No. 669,342, of March 5, 1901, i the heads or flanges be djustable relatively to each other and are connected to and automatically adjusted by the said hygrometricallyvariable means, although many of the claims herein are'not limited to the sheet-guides, flanges, or heads being attached to the spacing means.

The term core" is used above and in the claims for lack of any precisely-correct Word to cover scope intended, said term to be understood as covering any manner of hygronetrically variable or compensating support, carrier, spindle, tube, core, or spacer, so that it serves the function or purpose of the present invention.
